You are sneaky ------------
I suppose you could *coincidentally* arrive at the pool store the same time as your wife and ask the (ahem) POOL EXPERT (ahem) in front of your wife:
1. Is MPS non-chlorine shock an EPA approved sanitizer at pool temperatures? (No, kill time is too slow)
2. What is your scientific justification for selling me such a slow acting oxidizer instead of an EPA approved fast acting one like bleach/stabilized chlorine? Do you want my family to get sick or something?
3. According to your company's website, MPS is added to help reduce CC...isn't that right? I see on your test, my CC is zero and my FC is very high...Why do I need to add MPS?
4. Will you refund all my previous purchases of it, since you were clearly taking advantage of my beautiful, loving, and honest wife who trusted you to know what the heck you're selling?
With your kit, as long as MPS wasn't added in the last week, you'll know EXACTLY what your pool needs (and everything it doesn't). You could make her your suggested shopping list and dosing schedule and ask her what the Expert thinks about it. It might look like this:
40 oz of 8.25% sodium hypochlorite once daily (or more as needed to maintain FC of X for CYA of Y)
and nothing else until PH is less than 7.2 or more than 7.8 or CYA is less than 30. Ever.
